What size reservoir are you using? I saw a [H] thread where he used a 55gal water barrel. That seems unnecessary to me.
I am looking at using an aquarium canister filter. Res and pump all in one with shutoff and disconnect all built in. Probably a
Fluval 406 to start as I have a couple for our turtles (don't ask how we ended up with them ... lets just say my wife can be impulsive and they looks so cute when they were the size of a quarter) so I have some experience of them. Think I have already posted the specs but here they are again.
Flow Rate: 1450 LPH (383 US GPH)
Head Height (max.): 2.25 m (7.5 ft)
Media Capacity: 8.5 L
Wattage: 120 V/60 Hz – 23 W and 230-240 V/50 Hz – 20 W
Dimensions (L x W x H): 25 x 20 x 50.8 cm (10 x 8 x 20 in)
So it has 8.5L canister capacity with enough pressure to push to the top of rack give or take any pressure reducing bits I put in). I still have to check the hose diameter but the other advantage for me is all the filters etc I will take out and use for spares in my own turtle filters.
One thing about these canster filters is that they are tall. The 406 is around 10U plus connectors and pipes coming out of the top. This is fine for me as my rack is fairly empty but I may have to look at a wide / deep solution after the initial PoC is done.
My main effort at the moment is getting a safety case built around the CNC machine. This would seem to be fairly trivial to most but in Singapore, I have no workshop, shed, loft, basement etc so I am very limited as to where I can do any cutting and building. Materials are not so easy to get either. No big DIY Superstores where I can get the acrylic, alu channel, silicon etc, everything has to be sourced from multiple specialist shops all over the island.... It is a pretty big PITA, especially without a car (for those not aware, to give an idea, a BMW 320i over here is approx US$215,000 new. An entry level Chevolet Cruze is around US$91,000. Cars are also scrapped after 10 years unless they receive 'Classic' status).
Man, this looks way cool. C6100 watercooled is just awesome.
. Some way to go yet though. Have some more endmills (CNC cutting bits) on the way. Feeling more confident witht he tool now though and the CAD / CAM workflow.
Nice updates.
Thinking about the mobile rack you mentioned, mounting your rads at the bottom back of your rack with a res occupying some of the space in front (still letting enough air through) would look slick. Should only take up 3U as well. Fabricating a shroud to hold the fans back from radiator would help eliminate the centre deadzone where the fan motor/hub sits. I'd definitely recommend mounting the res and radiators at the bottom if it has a good seal, even if it means you can't have an upward venting radiator top of stack. If your load usage is intermittent then a decent sized res should allow you to ride out the fluctuations better and potentially get by on a smaller/fewer radiator(s) (sized only for worst-case scenario), should your cooling requirements increase/be insufficient you could look at adding an additional radiator and re orientating to the sides of that rack level.
That said, a smaller res would allow you to potentially mount a switch and/or short depth chassis in front, but might limit your ability to add additional radiator capacity (short of sandwiching).
I can see the main problem being the rear door blocking the hot air escaping where as having the rads at the top would allow venting vertically out through the vents for the top fan panel. Having said that, I do like the idea of having the water as low as possible to try to avoid a shower situation due to any critical failures.
Oh and my Makita cordless hammer drill (like this but clean and looked after
Makita 8400D), given to me by my father when I moved over here 8 years ago, has finally given up. Well TBH it is probably just the batteries that have died after serving my father and then me pretty well for lots of years. Whilst I could get a replacement battery, I deviced to take a look at what is currently on offer. I ended up getting a
Bosch GSR 10,8-2-LI Pro which is tiny but is sort of like a Star Trek phaser (it even has a light) so I just had to buy it
. Seriously though it is quite nice, tiny compared to the Makita with 10.8v rather than the Makitas 9.6v. The Makita has the hammer action for concrete but if I am going to drill concrete I will use my
GSR 21-2 RE Pro.
